In the 68th minute, Anas Al-Jbarat scored Al-Faisaly's second goal of the match as they were mounting a comeback from 3-1 down.
But it was his strike that also triggered the first three of five red cards in a ludicrous finale.
Al-Faisaly's Mohammed Shishani and Ahli's Walid Ziad and Yazan Thalji were all sent off when a scuffle ensued after Al-Jbarat's goal hit the net.
The match took an even more bizarre turn in the 87th minute as Al-Faisaly's Rwad Khizaran was shown a second yellow, having scored a dramatic equaliser to level the tie at 3-3.
Khizaran appeared to elbow Al Ahli's Obaida Al-Samarneh as he ran with the ball back to the halfway line. Al-Samarneh did appear to push Khizaran, though, so he was also sent down the tunnel.
In a game filled with drama and controversy, nine-man Al-Faisaly completed their remarkable comeback with a headed goal in seventh minute of injury time, before the home fans spilled onto the pitch in jubilation.
Enjoy the highlights below – not bad for a group stage match.
